Quickscoping is very common, many people play like -Endite.
The editing is quite bland which is very unusual as Emnesty has displayed good skill in video editing, he would never release something as prematurely edited as those videos.
Watch Scirca's video and you'll notice subtle differences in gameplay.
Not Emnesty nuff sed.

Plus. knowing Emnesty, he doesn't put Junk Flea clips into a montage
and when he makes montages, he makes it so that most of the time, the kills are on beat with the song / the song goes well. he's good at blending.
